how flat is flat-nose for tube mag?
Problem: I ordered a flat nose mold for my 1895 marlin, and when I received it the flat part of the bullet was somewhat small. (about 1 hundreth smaller than the primer pocket). Will this mold work as-is, or do I need to enlarge the flat?
Any help would be much appreciated.

Here's the best I could do. Various cartridges- 45 Colt, 38 Spl, 357 Mag, 375 Win, 30-30 Win, even 45 ACP for straight wall, lay-flat comparison. There are two RN in the mix- a 45 ACP, and a 45 Colt, and a 38 Spl WC in there, too.
You can see what would cover some primers (if they were there!), and what doesn't, and what dead centers a primer (RN's go into the large primer pockets!) in the way they lay in the tube. There are large and medium meplats otherwise.
You can see why the 30-30 factory RN's might not hit a primer as easily- they lay way down in the tube.
While doing this, I happen to think that a weak magazine spring would allow the cartridges to move during recoil more than a strong one, or one with a full tube. Maybe that is what happened to Muskeg13's rifle. Maybe a high primer, too? Whatever happened, everything came together to go bang in the wrong places.:shock:
